Original question:
We are using 2 stepper motors with DRV8711 with mosfet CSD88537ND. After setting up the various parameters of the driver IC as per our requirement, we are facing the issue of predriver fault and undervoltage lockout fault. Sometimes it will make 1 or 2 revolutions before the fault and sometimes it will only rotate for a tiny amount and fault appears. Each time when we clear the fault and the motor will begin to turn and then the fault will trigger again.So please provide me with the solution to troubleshoot this problem.
